How to Complain About a Builder to RDA, LDA or CDA in Pakistan

To complain about a builder or developer who ignored an approved plan, built without one, or missed a handover date, write to the development authority that controls that land: RDA in Rawalpindi, LDA in Lahore, CDA in Islamabad, or SBCA in Karachi. Give your plot number, the violation in plain words, photos, and your CNIC. The authority can inspect the site, issue a notice, and seal or demolish what was never approved.

We get this question a lot in two shapes. One is a neighbour who added two floors nobody approved. The other is a developer whose sales office stopped answering calls two years after the handover date it promised. The forum is almost never the police station first. It is the authority that stamped the plan, because only that office can seal a building or strike a layout off its own record.

Your complaint goes to whichever authority approved the plan

Pakistan has no single national housing regulator. Each city's development authority polices its own area, and a complaint sent to the wrong one simply sits unread. Match the plot's address to the authority, not the builder's head office address.

Rawalpindi and the cantonment areas around it fall under the Rawalpindi Development Authority, RDA. Lahore falls under the Lahore Development Authority, LDA, unless the project sits inside a cantonment, in which case the relevant Cantonment Board handles it. Islamabad falls under the Capital Development Authority, CDA, the same office that signs off a building plan before construction starts, under the CDA Ordinance 1960 and the ICT Building Control Regulations 2020. Karachi falls under the Sindh Building Control Authority, SBCA, which works under the Sindh Building Control Ordinance 1979.

A housing scheme can also sit under a cooperative society or a private developer who has its own site office. Even then, the scheme's layout had to be approved by one of these authorities before a single plot could be sold, so the complaint still goes there.

Gather proof before you write a single word

An authority acts on specifics, not on frustration. Bring the plot number, the scheme's name, your ownership or allotment paper, and photos or a short video of the actual violation, dated if your phone does that automatically.

If you have a copy of the approved plan, even a photocopy from the time of booking, attach it. Comparing what was approved against what stands on the ground is the fastest way an inspector can act, rather than opening a fresh investigation from zero.

• Your CNIC copy. No authority entertains an anonymous complaint; your name has to be on it.
• The plot or file number. Not the house number painted on the gate, the authority's own file reference if you have it.
• Photos or video of the extra floor, the encroached setback, or the unfinished block, taken from a public street if you cannot enter the site.
• Your allotment letter, builder agreement or sale deed, especially for a delay complaint, since it carries the promised handover date.
• Any earlier notice the authority itself issued to that site. If one is already pinned on the wall, photograph it too.

File the complaint in five steps

None of the four authorities charge a fee to receive a written complaint against a builder or an illegal structure. The fee only appears later, if you are the one applying for a building plan or a completion certificate, not for reporting someone else's violation.

1. Write a one-page complaint. State the plot number, the scheme, the exact violation, and what you want done, sealed, demolished, or the layout corrected.
2. Attach your evidence. CNIC copy, photos, and the approved plan if you hold one.
3. Submit it to the right desk. That is the Building Control Section at CDA, the Land Use and Building Control wing at RDA, the Metropolitan or Building Control wing at LDA, or the SBCA zonal office that covers your area in Karachi. Each authority also keeps a One Window or front desk counter that will log and forward it if you are unsure which wing to name.
4. Get a receiving stamp or diary number. Ask the counter clerk for it on your own copy. Without this, you cannot prove later that you ever filed anything.
5. Follow up in writing after two to three weeks if nobody has visited the site, referencing your diary number.

The authority can seal, fine or demolish, not just warn

Once a complaint is logged, an inspector from the building control wing visits the site and compares it with the approved plan. If the structure goes beyond what was approved, the authority can issue a show cause notice, then seal the building, and in Sindh specifically, order demolition.

Section 7-A of the Sindh Building Control Ordinance 1979 lets SBCA order a building demolished at the owner's cost, without needing a separate court order first, where construction went ahead without the approval Section 6 requires. Islamabad and Punjab authorities use their own ordinance and regulations to the same effect, sealing first and demolishing where the owner does not correct the violation.

None of this moves on its own clock. These authorities run demolition drives in waves, often after a court pushes them, and a single complaint can sit for weeks before an inspector turns up. That is not an excuse to stay quiet, it is a reason to follow up on paper rather than by phone call alone.

In Lahore, a building that was never issued a completion certificate on finishing has already failed one official check, which makes a later violation easier for LDA to act on, since there is no sign-off to defend.

A delayed handover is a different complaint from an illegal structure

If the builder followed the approved plan but simply did not hand over your unit on the date the agreement promised, that is a contract dispute, not a building control violation. The development authority will not chase your refund or your rent for the delay; its job is the structure, not your agreement with the seller.

For a pure delay with no plan violation, the usual route is a civil suit for specific performance or damages, or a complaint under your province's consumer protection law if the builder sold you a service it did not deliver on time. Keep every payment receipt and the signed agreement; without them, a delay claim has nothing to stand on.

Checking a scheme's own approval before you ever sign anything avoids most of this. Before paying a token or booking amount, it is worth seeing whether a housing society is approved by the authority it claims, since an unapproved scheme has no layout for anyone to enforce later.

Escalate if the authority sits on your complaint

A diary number is not the end of the process if nothing happens. Each authority has a tier above the front desk that exists exactly for this.

1. Write to the Director or Director General of the relevant wing, attaching your original complaint and diary number.
2. Approach the provincial ombudsman for maladministration, Wafaqi Mohtasib for Islamabad and federal bodies, or the provincial Mohtasib's office for Punjab and Sindh matters, if the authority has simply not responded.
3. File a writ petition in the relevant High Court as a last resort, which is how most of the larger sealing and demolition drives against illegal housing schemes actually started, from a citizen's petition rather than the authority acting first.

Common questions

Which authority handles a builder complaint in Islamabad?

The Capital Development Authority, CDA, through its Building Control Section, under the CDA Ordinance 1960 and the ICT Building Control Regulations 2020.

Does it cost anything to file a complaint against a builder?

No. Filing a written complaint about an illegal structure or a violation costs nothing at any of the four authorities. Fees apply only to your own building plan applications, not to reporting someone else's.

Can a development authority demolish a building without going to court first?

In Sindh, yes. Section 7-A of the Sindh Building Control Ordinance 1979 lets SBCA order demolition directly where construction had no approval under Section 6. Other provinces follow a similar notice-then-seal pattern under their own regulations.

What if my complaint is about a delayed handover, not an illegal structure?

That is a contract issue between you and the builder, not something the development authority enforces. Pursue it as a civil claim or a provincial consumer protection complaint, with your agreement and payment receipts as proof.

How do I know which authority covers my plot?

Match the city, not the builder's office address. Rawalpindi and its cantonment belt go to RDA, Lahore to LDA, Islamabad to CDA, and Karachi to SBCA. A scheme inside a cantonment goes to that Cantonment Board instead.

What proof should I bring when I file the complaint?

Your CNIC copy, the plot or file number, dated photos or video of the violation, and the approved plan if you have a copy, plus any earlier notice already pinned on the site.

How we verified this

What we checked, where we read it, and what we could not confirm.

Last checked 5 October 2026. The Punjab Development of Cities Act 1976, Section 39, underlies RDA's enforcement powers against unapproved construction. The CDA Ordinance 1960 and the ICT Building Control Regulations 2020 govern Islamabad. Section 6 and Section 7-A of the Sindh Building Control Ordinance 1979, the latter added by the Sindh Building Control (Amendment) Ordinance 1982, govern Karachi and were read from reported High Court of Sindh case files citing both sections directly. Contact details for each authority's building control desk change between offices and press announcements more often than we could verify on each authority's own page by publish time, so none are stated here as fact; confirm the exact desk and phone number at the authority's office or website before you travel to file.
